STEAM-GENERATOR FOR ROAD-VEHICLES OR OTHER PURPOSES.l

SPECIFICATION forming part of Letters Patent No. 263,954, datedSeptember 5, 1882.

Application filed November 9, 1881. (No model.)

To all whom it may concern.:

Be it known that I, FRANKLIN D. P1EEcE,a citizen of the United States,residing at Butt'alo, in the county ot' Erie and State ot' New York,have invented a new and .Improved SteamGenerator for Road-Vehicles orother Purposes; and I do hereby declare that the following is afull,clear, and exact description ot' the construction and operation of thesame, reference being had to the accompanying drawings, making apart ofthis specification.

The object of my invention is to furnish a light, compact, and cheapsteam-generator for the driving mechanism for roadvehicles,which Will befully and clearly described hereinafter by reference to the accompanyingdrawings,I in which- Figure l is a vehicle showing my inventionconnected thereto. Fi g2 isaplan or top view of same. Fig. 3 is avertical'cross-section on line X X, Fig. 1, through the reservoirs andthe seat. Fig. 4 is a horizontal section of the reservoirs for fuel andwater. Fig. 5 is a vertical section through the steam-generator on anenlarged scale. Fig. 6 is a cross-section on line z z, Fig. 5, on anenlarged scale, looking to the left of the sheet orto the rear ot' thevehicle. Fig. 7 -is a horizontal section of the steam-generator on linew w, Fig. 5.

A represents the frame or body of the vehicle, which is constructed ofthe usual materials.

A' are the driving-wheels, rigidly secured to ever, they may be placedloosely on the axleshaft and fastened thereto by a clutch mechanism,whereby the outer wheel may be.permitted lo make a greater number ofrevolutions than the inner in rounding a curve; or they may be placedloosely 011 the axle a? and the sprocket-wheel g secured to the hub ofthe oli' wheel,in which case thatwheel only serves as a driver.

O represents the seat ot' the vehicle resting upon and secured to theframe or bodyA by the supports P `l?, which may be constructed of anysuitable material.

C is the Water-reservoir, which is secured to the under side of the seatand provided on its upper side with a screw-cap, c2, extending Inwide-track vehicles, hoW- upwardly through the opening b b in the seat.By removing the cushion ot' the seat and tho screw-cap c2 the reservoirmay be filled.

The water-reservoir O is provided with perforated`comInwnicatinglcompertinents c5, (see Figs. 3 and 4,) for the purposeot' preventing the swashing of the water while the vehicle is in motion.

The fuel-reservoir C2 is arranged Within the reservoir C', so as to besurrounded by water, which keeps it cool and prevents evaporation andall danger of explosion.

D represents the usual curved reach, the rear ends of which are securedto the under sides of theA frame A by bolts d d, or in any otherwell-known manner. l A

E (see Fig. 2) is the engine, arrangedvhorizontally within acasng, O, ofwood or other suitable material. The top of the casing O is made in twopieces, which are hinged so that lthey may be opened to get at theengine. The

bottom of the casi ng O may be constructed of zinc or other suitablematerial. The object ot' this casing O is to keep the engine clean or`free from dust or dirt.

f represents a ily-wheel arranged on the crank-shaft c, so that it maybe conveniently reached by the hand of the driver in starting theengine.

The cylinder ot' the engine and the guide for the piston-rod are securedto a bed-plate, E', which in turn is secured to the under side of theframeor body A.

The steam-generator consists essentially of` coils of tubing, (two inthis case, h h2, Fig. 5.) The coil h2 surrounds the coil It', and bothare connected at their ends with a cylinder or stand-pipe, H, which issecured to the casing N, and which is provided with a water-gage, h5, asteam-gage, t, and a spring or pop safety-valve, i', and which issupplied With water through a feed-pipe, I. The water entering thecylinder or stand-pipe H from the upper ends of the coils h h2 falls,and again enters them at their lower ends, while the steam rises to theupper part of the cylinder or stand-pipe H, from which it is conductedto the engine ll. The coils h h2 are inclosed by a metallic casing, h3,which is secured to the casing N, and which may be provided withinwardly- IOO y X, which is secured to theframe A and stayed side of thecasing N and to the under sido of y generator there is no shell toexplode, and the tubes of which it is composed are capable of iprojecting hooks to assist in the support of the l coils. The metalliccasing is covered with asbestus felt, or some other suitable non-con`ductor, h4, (see Figs. 5 and 7,) and the entire generator, except theupper portion of the stand-pipe H, is inclosed by the wood casing bybraces n n', secured to the lower and rear sustaining a very highpressure. Hence it is comparatively' safe, and, having a largeheating-surface and a rapid circulation, itgen'er- -ates steam in largequantity and quickly for its size and Weight; hence its adaptability forthe' purposes set forth.

I lay no claim to the vehicle or carriage in this application alone, ofitself considered, as I may make that the subject of another'application.

. I claim as my invention- 1. A water-reservoir surrounding afuel-reservoir and having a series of perforated plates, substantiallyas shown, for the purpose of prein combination with a feed-pipe, I, anda steamgenerator, as described.

2. A steam-generator provided with a suitable hydrocarbon-burner andWaterand fuel reservoirs, substantially as specified, in combinationwith a steamengine inclosed within a casing and the running-gear of aroad-vehicle, substantially as and for the purposes described.

3. A steam-generator consisting-of the coils venting the swashing orpitching ofthe Water,

h h2, inclosed Within a non-conducting cas- 4. rlhe water and fuelreservoirs C C2, ar

ranged below the seat C, in combination with the pipe Z,burner L, and asteam-generator, as and for the purposes described.

5. A steam-generator consisting of the coils hy h2, inclosed withinanon-conducting casing, and provided with a stand-pipe, H, and ahydrocarbon-burner, L, in combination with feedpipe I` and awater-reservoir, C', arranged below the seat C, as and for the purposesspecitied.

ln testimony whereof I affix my signature in the presence of twosubscribing witnesses.
